NP Analytical Laboratories (NPAL) was founded in St. Louis, MO in 1916, on the second floor of a building on the corner of Eighth & Gratiot. It was here that Mr. S. Merrill started the chemical analysis laboratory - one of the first quality control laboratories in the feed industry. Today our chemists and microbiologists are recognized industry leaders in food and feed testing. We work closely with research and quality teams to implement test methods that keep NPAL at the forefront of testing laboratories.
We are proud to continue our 100 year tradition of providing state-of-the-art testing and consulting to support research, product development, and product quality.
